Urgent Query on Sponsorship in DS160

[daug2016]

Hi,

My parents and in-laws have submitted DS160 by mentioning that they will sponsor for their respective trips to USA.This is because my L1 expires in Oct 2017.Now I realized that we can sponsor for our parents and in-laws as far as our Visa is valid.Hence I would like to sponsor the trip and change the details in DS160. Could you please let me know how to proceed ?Or if there are any other alternatives ?
Visa fees has been paid ,appointment has been scheduled for Feb 2017 and DS160 has been submitted for parents and in-laws.Kindly suggest.Thanks.

You can't make any changes in ds-160 form once you have already paid fees and scheduled appointment. You have to cancel the current one and schedule new appointment with new bar code after filling new ds-160 form.
